Be it known that LWTILLKAM H. 51eme, ai citizen of the United Sietesa resident vof ievelimdounty of Quyehegs and State o? hio, have invented new and usefui m proveniente in Drag Links, of which the foie lowing is -a .speci1cstic-1nl the principle 'of the invention being heiein expiaine, emi the best mode in which :i have con'eempleefi appiying that principle.; so as to fiistiuguisii it from other inventions.

My inventionl-eleiee to drag iinks oi' use as a art of 'the steering meiieiiism of suenmob es, and particularly to appara-tus ai' @his ehiuacieiof the welded type. My ventio'n also reistes eo drug iinksoif ziie ioe'f ing typea i. e.7 the bearings are. io {ioe inside ihe usiiai emi sockes ami cono'm. to any irreguisrities of'he steeiig alim emi axle erm baiis., The object of the inveneion isl to provide e, welded iis; im which Miiculties ue to weaimess oecesione by welding and dee to flaws in the weliiiig are mgely eliminated. This is accomplished in geneiai by provieig ehe weing piene in e compestiveiy large seoion of the iim,

Refering to he annexed dawing in which the same pests aire indicated in the several figures, respeotvefly9 by the same ordineis, a piece of see tubing'is indioeed by the oidinei whose eiis f2 -iiave been upset and then expended so isiiet'saifi eX- panded ends have a, Well thickness equal to the Weil thickness of tile origii'isi piece oi: `tubing; 1.

L img smiwie Zilli smaiier innenends" eiwtiieseetiens et the more liable te be fatei'tiiai'x is' true in my neir andinlpreved construction shown in the accompanying drawing, heretefere described and hereinafter claimed, in which the Welding aires is in the largest section ofthe tube.. Even in the case of the steering arniejnd ef the tube, wherein the welding aree. intersects the suiuiier portion 6 oi the bidi' entry t3? due to the reit/ive arrangement of the spring and bearings in the lefthand socket 4, Figure 2, stili, the solid materiei in this Welding area is greater than would be the soiidv materiali .in any welding aree through the smaller intermediate tube l'.

Wiet i. daim is:

l. A. drag; link. consisting et a piece et tubing expended at, the end to ferm an in tei-nul shouider providing a seat and an expanded end in the form et a short cylindricai fienge of greater diameter than said tubing; and a seeond piece of tubing, et the sel-me outside diameter as seid expanded end,

butt-WeldedI to said end to 'form en end socket.

2. A drag link consisting of a piece et tubing:r upset and expanded at the end to forni an internal shoulder providing; a seat and an expanded end in tile forni of a sh'ort cylindrical flange et greater diameter than said tubing, the wall et said expanded end being of the saine thickness as the original tubing; and a second pieceof tubing, of the same outside diameter and wall thickness as said expant'led end. butt-welded te said end to Yform an end socket.

3. A drag' link consisting et' a piece ef tubing upset and expanded at its ends te form internal shoulders providing seats and expanded ends in the ferm ot short cylindrical anges of greater diameter than said tubing, the walls of said expanded ends being of the same thickness as the original tubing; and other pieces of tubing, et the same outside diameter and Wall thickness as said expanded ends, butt-Welded te said ends to torni end sockets.
